$PECIFICATIQN forming part Of Letters Patent N 0. 734,729, dated July 28, 1903. Application filed July 18, 1902 fierial No. 116,115. (No model.)

To all whom it may concern.-

Be it known that I, MAX MERTENS, a subdifferent from the ordinary cards in having a large number of very small holes which lie very close together and require a consider-j able exactness in their position withregard;

as the holes which may be punched at most in the card. Below the guide-plate, with its stamps, the blank card is positioned. Over said guide-plate a striking apparatus is arranged, adapted to travel in its longitudinal direction, being fitted with one or several transversal'rows of striking-needles that are operated by a keyboard, which according to I the pattern or designs causes the stamps to punch the blanks. p v

. The machine of such invention is fully set forth and described in the following specifiof frame 1.

cation, of which the accompanying drawings form a part, wherein similar numerals of reference designate like or equivalent parts wherever found throughout-the several views, and in which- Figure 1 is a vertical elevation of the machine, partly in section. Fig. 2 is a cross-section taken at right angles on Fig. 1. Fig. 3 is aplan of the machine, partly in section. V

1 is the framework of'the machine, having located in suitable bearings 2 on each side the horizontal shafts 3, to which are keyed the wheels 4, adapted to receive and hold the card-blank 5, that is guided over the table 6 This table carries a U-shaped beam 7, leaving room enough between itself and the table 6 to allow the blank to pass under said beam.

number of stamps or punches 8, by which generally speaking,

In the same are guided a the blank 5 should be provided with holes. Besides, in saidbeam 7 the stamps 8 are also guided in a bridge 9, arranged within the beam and being likewise U -shaped. The stamps 8 are provided each with a head, and with them correspond in number and are arranged above them two transversal rows of striking-needles 10, that at their bottom ends are guided in a plate 11 and in running upward being bent asunder and guided in the top pose operated by a keyboard, which, according to the pattern, regulates the needles to be extended to the operation of a striking-piston, as maybe understood from the following: On' the carriage 13 is mounted a cylinder 14, in which is guided a piston 15 by means of a rod 16. Said rod is-coupledrwith a doublearmed lever17, turnabl'e on an arm 18, which is connected by a bar 19 to a lever 20, sitting on a shaft 21. Said lever is locked in its position in the following manner: On a bolt 22, Fig. 1, is turnably secured a three-armed lever 23, the vertical arm 24 of which is slotted and adapted to guide a pawl 25, which is pivoted to lever. Said pawl engages a ratchetwheel26, seated on shaft 21, and it will be clear that during the engagement of pawl 25 with the ratchetwheel 26 the lever 20 is locked in its position, resting with a set-screw on asupport, and the piston 15, which underlies the action of a spring 27, is prevented from going down and striking the needles 10.

The manner in which the piston may be releasedand allowed to operate will be understood from the following: The bottom of the piston is formed to a dovetailed projection 28, to both sides of which on spindles 29 arms 30 are arranged, having an ear 31 and an extension 32, which corresponds with a needle below it when its arm 30 is operated by the keyboard and out of reach when the said arm is withdrawn bya spring. In the first case the needle would beoperated and drive the stamp 8 through the blank. In the other case the needle would remain unmoved. The

movement of the arms 30 is obtained by a keyboard 33, having a number of'keys 34, which correspond to the number of strikingneedles and which are pivoted to a shaft 35. On the other end of each key bears a rod 36, which being angularly bent, so as to form an angle-lever, is .journaled in a frame 37 and provided with'an arm 38, that by means of a rod 39 is connected with the ear of arm 30, and it will now be clear that according to the play of the keys 34 more or less arms 30 are pushed under, and the piston corresponding thereto their needles 10 are exposed to the action of the piston 15. By the same keyboard also the releasing and locking of the piston and the traveling motion of the whole punching apparatus are carried out. For this purpose underneath the keyboard 33 a rod 40 is arranged, being formed at both ends to double-armed levers 41 and pivoted to bolts 42. With lever 41 are connected levers 43, keyed to a shaft 44, on which is fixed another lever 45, which by means of a rod 46 is connected with one arm of the three-armed lever 23, and from the foregoing it will now be understood that when the keys 34 operate and have the needles 10 adjusted with respect to the striking-piston the following takes place: When pressing the key down on said rod 40, the levers 41, 43, and are oscillated and the three-armed angle-lever 23 turned around its fulcrum 22. This turning will cause the pawl 25 to be removed from the ratchet-wheel 26, and now lever 20 is freed and spring 27 can force down the piston 15, so that the arms 30 may strike the needles 10, being within reach of them, and the needles can drive the stamps 8 through the blank to punch the holes therein as desired. The piston 15 will be now returned in its normal position for this purpose. To shaft 21 of the ratchetwheel is keyed a pulley 47, on which is fixed a cord 48, carrying a weight 49. As soon as the angle-lever 23 is turned and the pawl 25 removed from the ratchet-wheel 26 the latter is caught by a pawl 50, projecting from arm 51 of angle-lever 23, which entering said wheel prevents any movement thereof during.

the striking operation of the piston. Now after the key 34 has been let free by the operator a spring 52 draws angle-lever 23 back in its normal position until the set-screw 53 rests upon its support 54. The pawl 25 is then inserted again into the ratchet-wheel 26, engaging another tooth than before, and pawl is taken out of the ratchet-wheel. The weight 49, turning the ratchet-wheel, has lifted the piston 15, which is locked again, as before described, and the ratchet-wheel 26 is turned one tooth forward, all by the action of the weight. The turning of the wheel 26 causes a traveling of the carriage 13. Said carriage is provided with the shafts 55 and 21, fitted with wheels 58, that are adapted to runbetween the rails 56 57. The shaft 21, carrying the ratchet-Wheel26, has keyed thereto a pinion 59, meshing with a rack 60,

and from the foregoing it will be understood that during the turning of lever 20 down on its seat the striking-piston is lifted and the carriage 13, on which all the operating parts are mounted, is traveled in order to act on the following row of stamps.

In order to return the stamps driven through the blank to their normal position, the U-shaped bridge 9 is raised, lifting thus the stamps by hearing under their heads.

The bridge 9 may be operated by hand or foot or mechanically. In the present example I have attached to the bridge a lever 61, to which a rod 62, operated by foot, is suspended.

In the description I have shown that the blank and the stamp-holding plate are held fast and the striking-cylinder, keyboard, &c., are traveled over them. It is, however, of no importance for my invention to arrange the parts contrary, so that the striking parts are unmovable and blank and stamp-holding plate are traveled. It is also of no importance whether by means of the keyboard all the operations described are carried out or whether the keyboard serves only for adjusting the striking-needles and the operation of the striking-piston and the traveling of the respective parts are efiected by other means, the essential feature of my invention consisting in the separate arrangement of a holepunching device of any desired exactness and a striking apparatus, and by such combination the said Verdol cards may be manufactured in the same way as the ordinary jacquard-cards.

What I claim, therefore, and desire to secure by Letters Patent, is

1. In a machine for punching jacquardcards of the Verdol system the combination of a stationary framework, having means to' receive and hold and travel a card-blank, a stamp-holding devicev arranged above the blank and havinga vertically-movable bridge, means to operate any number of stamps and means to raise and lower the stamp-guiding work containing a sufficient number of striking-needles to engage the stamps, said framework being adapted to travel transversely to the blank, means to adjust the striking-needles and means to operate the same substantially as described.

3. In a machine of the character described a framework to receive the blank, a stampholding device arranged above the blank, means to raise said device, a framework containing a number of striking-needles above the stamps, a striking-piston, means to lock said piston in an elevated position, and means to start it after being released substantially asdescribed.

. 4. In a machine of the character described a framework to receive the blank, a stampholding device arranged above the blank, means to raise said device, a framework containing one or several transversal rows of striking-needles above thestamps, a strikingpiston having a projection, pivotally-secured arms engaging said projection, a keyboard being connected with said arms for the purpose described and set forth.

5. In a machine of the character described a framework to receive the blank, a stampholding device, a framework having needles, astriking-piston, a keyboard for adjusting the needles, said framework, piston and keyboard, being operatively mounted on a car- MAX MERT'ENS.
